AI PARATUS FOR DYEING YARN- Application filed November 3, 1927. SerialNo. 230,849.

This invention relates to an apparatus for dyeing yarn, and I would haveit understood that I employ the term yarn in its broadest sense toinclude thread of any character wound on a bobbin in the form of amp,the apparatus being especially designed for permitting the dye or otherliquid to be forced by pressure through the yarn on the perforatedbobbin.

The invention consists in certain novel features of construction andcombinations and arrangements of parts as Will be more fully hereinafterdescribed and pointed out in the claim. In the accompanying drawings-Figure 1 is a view in longitudinal section showing a plurality ofbobbins on a liquid supply tube through which the dye or other liquid isforced through the tube and the yarn;

Figure 2 is a perspective view showing a single cop or bobbin with theyarn wound thereon ready for use Figure 3 is a view in side elevation ofmy improved tube; Y

Figure 4 is a perspective view of a closure cap ring;

Figure 5 is a view in section showing the tube on a wooden bobbin whilebeing filled with yarn.

1 represents my improved bobbin which is in the form of a tube having anotched or serrated end 2 and provided throughout with perforations 3. 4is the yarn or cop wound or otherwise formed on the bobbin 2,

and it will be noted that this cop has tapering ends and that theliobbinhas smaller perforations adjacent the ends than at its intermediateportion Where the cop is thickest, so that there will be an evendistribution of the dye or other liquid through the cop.

5 represents a perforated tube which is supplied with dye or otherliquid under pressure, and on this perforated tube I 10- cate chokerings6 and 7 which are frictionally or otherwise held on the tube. The ring 6receives the notched serrated end of the bobbin 2, and the ring 7 hasannular flanges 8 and 9 which extend into the space between the bobbinsand the tubes to hold the bobbins and the tubes properly spaced.

.tubular bobbins 1 in position on a wooden I also employ a second ringGat the outer end of the series of bobbins to close the space between thebobbins and the pipe 5 to prevent the dye or other liquid passingthrough the end of the bobbin. In other words, I may provide on a singlepipe 5 a series of bobbins coupled together and spaced from the pipe onwhich they are located, n both pipe and bobbins being perforated so thatwhen the liquid is. forced into the pipe it. will pass through the)erforations of thee pipe and the bobbin and t rough the yarn or v copso as to dye or otherwise treat the same.

I deem it important that the perforated 3 bobbins be spaced from theperforated tube to prevent any possibility of the perfora tions beingclogged and to allow a free circulation of the liquid and I of coursedeem it important to socouple the bobbins with relation to the pipe asto properly guide the liquid and prevent its squirting .or escaping fromthe ends of the bobbins;

,I have illustrated in Figure 5 one of the bobbin 10 while the yarn iswound on the tubular bobbin before the dyeing operation.

While I have illustrated what I believe to be a preferred embodiment ofmy invention it is obvious that various changes and alterations might bemade in the general form of the parts described without departing frommy invention and hence I do not limit myself to the precise details setforth but consider myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of the appendedclaim.

I claim: a v An apparatus of the character described, comprising aperforated metal yarn receiv ing bobbin adapted to fit over a spindle ora dye directing pipe, said bobbin having a serrated end adapted toengage a correspondingly shaped part on a spindle or tube to lock theparts against independent turnin igned at Valdese in the county of Burkeand State of North Carolina this 31st day of October, A. D. 1927.
